Features and benefits

TMR triple redundancy communication: Three independent channels for reception and voting, no single point failure, SIL3 safety communication

Multi-protocol Ethernet: Supports Modbus TCP, etc., seamless connection to DCS, HMI, and upper computer

System expansion and data bridging: Connect remote I/O stations, third-party safety systems, to achieve cross-system data sharing

Comprehensive diagnosis + hot swapping: Real-time diagnosis of communication links, ports, and protocol failures, online replacement without stopping

High anti-interference and safety isolation: Electrical isolation between network side and system side, suitable for industrial strong interference environments

Typical applications

ESD system and DCS communication: Two-way interaction of SIS interlock signals and process parameters

F&G fire protection system networking: Alarm and status upload of fire protection system to DCS / monitoring platform

Remote I/O expansion: Connect remote I/O cabinets to extend the distance for signal acquisition in the field

SIL3-level safe data exchange: Safety communication links in high-risk industrial environments such as chemical, oil and gas, and power industries
